In recent years, ultrasonic-assisted machining (UAM) has been widely implemented to improve the performance and element quality of machined products. This paper comprehensively reviews the ultrasonic vibration effects on such ultrasonic vibration-assisted (UVA) processes as hobbing (UVAH), lapping (UVAL), electrochemical gear machining (UVAEGM), honing (UVAH), and grinding (UVAG), respectively. Compared with the conventional machining, the UAM significantly reduced the surface roughness, improved the surface microstructure, and quality. Considering the UAM applications surface modification and surface strengthening, the available technologies of ultrasonic impact, ultrasonic shot peening, and ultrasonic deep rolling were analyzed for gears and similar components. It was concluded that the surface was strengthened under UAM through introducing the high-amplitude and large-depth residual compressive stresses, restraining crack propagation to a certain extent, and improving the gear fatigue resistance. Finally, the ultrasonic machining effect on gear fatigue resistance was theoretically substantiated from the ultrasonic vibration system and surface integrity standpoints. This review aims to optimize the application of ultrasonic-assisted machining, in order to produce gears with enhanced fatigue resistance and surface integrity.

“…Despite its many advantages, studies on ultrasonic rolling [20][21] could not be directly applied to the strengthening on the gear surface. At the same time, previous studies showed [22][23][24][25][26][27] that the initial running-in of the gear, and appropriate load and speed improved the surface integrity and affected the contact performance of the gear. Considering the excellent characteristics of ultrasonic rolling and the positive influence of initial running-in on gear surface performance, a set of rolling enhanced acoustic system (REAS) for the gear tooth surface was designed in this study.…”

Parameters of gear flanks, such as roughness, hardness, and residual stress, impact their working performance. Therefore, it is essential to optimize these parameters for increasing gears' life. Thus, this study combined the meshing theory and the ultrasonic surface rolling technology, and presented an innovative design to realize ultrasonic burnishing. First， the dimensions of the ultrasonic burnishing device with two nodes integrated with a gear at the bottom were calculated using frequency equations by a numerical method. Second the correctness of the calculating results was verified by simulations and experiments. Third, the influence of the ratio between the width and diameter of the gear on the acoustic system was studied. Finally, experimental platform of the rolling enhanced acoustic system for gear tooth surface is built successfully. A series of experiments were conducted, and the results showed that the roughness decreased and the hardness and the residual stress improved. Therefore, this design provided a new theory and technology to machine complicated surfaces such as gear flanks.
